Amanda "Mandy" Barnes, LMFT
LMFT 139812
Clinical Supervisor
Mandy is a Clinical Supervisor and Licensed Marriage and Family Therapist who is passionate about fostering growth in both the clients she serves and the pre-licensed clinicians she supervises and mentors. She believes that healing and professional development begin with creating environments where people feel safe, supported, and understood.
Mandy earned her LMFT license in 2023 after completing all of her pre-licensure training under the supervision of Dr. Avis Attaway, Clinical Director at Life Source Affordable Counseling. That experience inspired her commitment to providing thoughtful, collaborative supervision and helping develop the next generation of ethical, compassionate, and highly skilled therapists. She is dedicated to strengthening her pre-licensed clinicians' confidence, clinical judgment, case conceptualization, and authentic therapeutic style.
In addition to her supervisory role, Mandy maintains a thriving private practice grounded in trauma-informed care and attachment theory. She is recognized for her ability to build strong therapeutic alliances, create emotionally safe spaces, and foster meaningful client engagement and effective treatment. Mandy believes that lasting healing occurs when clients feel secure enough to explore the root causes of their struggles to create a deeper healing experience. Whether supervising pre-licensed clinicians or providing therapy, Mandy considers it a privilege to support others in reaching their fullest potential through connection, growth, and lasting change.
